B&C

From the base shelf prospectus (p24):

"Although the Corporation is not currently taking any active steps to explore potential acquisition opportunities, it expects to do so in the near term. Growth through acquisition is common in the technology sector, and often required in order to achieve both technical and market penetration objectives. In terms of the Corporation's long-term technical objectives, the Corporation believes that it is essential to offer pluggable and other forms of transceivers to end-users, rather than to companies that design and sell optical modules. This type of forward integration is currently achieved by collaborations with other small to medium-sized companies, although the Corporation recognizes that this approach may not be suitable over the long-term. Similarly, backward integration into components, including the manufacture of lasers, is a typical path that has been pursued by other companies in the transceiver sector and may also be pursued by the Corporation in the future."

Certainly not a definitive statement for laser manufacture in the short term, but tells you something about their strategic planning and/or direction for the future.
